Abstract

The invention discloses a brazing material for aluminum-steel dissimilar-material connection brazing. The brazing material for aluminum-steel dissimilar-material connection brazing is composed of tin, lead, zinc, porous graphene, copper, nitrilotriacetic acid, aluminum base powder, zinc fluoride, tetrahydrofurfuryl alcohol and hydrogenated rosin. The copper is made into a strip, and the tin, the lead, the zinc, the porous graphene, the nitrilotriacetic acid, the aluminum base powder, the zinc fluoride, the tetrahydrofurfuryl alcohol and the hydrogenated rosin are mixed and solidified on the surface of the strip-shaped copper. Compared with the prior art, the brazing material for aluminum-steel dissimilar-material connection brazing has the advantages that the copper is used as the main raw material, the tin, the lead and the zinc are mixed with an combustion improver composed of multiple assistants, so that the copper can be rapidly molten, the welding efficiency is improved, and the brazing material for aluminum-steel dissimilar-material connection brazing has application value and popularization value.

Description

technical field [0001] The invention relates to a welding technology, in particular to a brazing material for brazing aluminum-steel dissimilar connections. Background technique [0002] The welding of aluminum alloy and steel is difficult to weld due to the large difference in melting temperature and the formed alloy is very brittle and easy to crack. At present, the ideal ones are as follows. 1: Friction welding, mainly suitable for shafts. 2: Explosive welding, mainly suitable for welding aluminum plate and steel plate. 3: Brazing, mainly using gas welding flame as heat source, melting lead solder for welding. In the prior art, the welding efficiency of brazing filler metals is relatively low, and continuous improvement and innovation are required in the spirit of excellence. Contents of the invention [0003] The object of the present invention is to provide a brazing material for brazing aluminum-steel dissimilar connections in order to solve the above problems. ...
